Profiling multiple Eclipse web services [message #48966] Tue, 03 January 2006 17:52 Go to next message

Originally posted by: jkp1974a.cox.net

Hello everyone.

Ideally, I'd like to run 3 different web services (not related in any
sense) using the bottom up web service wizard. In addition, I'd like to
profile them using the TPTP project.

However, I have a bunch of questions.

Is it possible to use the TPTP project (v. 4.2) with web services in
eclipse simulatenously? (Sorry if I should post in the WTP group...).

If I wanted to profile 3 web services, would I need to open 3 separate
instances of eclipse? Do I need a copy of the agent controller for each
web service? Do I need a separate java VM for each one as well?

I am running Windows XP SP2, Apache Tomcat 5.5.12, Eclipse 3.1 w/ WTP 1.0
(and all requirements).

Thanks in advance to anyone's replies and answers. They're greatly
appreciated.

Ken

Hi Ken,

I hope I can answer some of the questions.

It is possible for TPTP to profile 3 different web services at the same
time. You will need:
- One copy of Eclipse with TPTP
- One Agent Controller per machine running web services

If you want to separate the profiling information for those 3 web services
then you will need to start each of them with its own jvm instance.
Otherwise the profiling data will be merged together. You will need to add
the "-XrunpiAgent" jvm argument to each of the jvm in order for TPTP to
attach to the java profiling agents.

This may be a typical setup:
1. Install, configure, and start Agent Controller
2. Start Eclipse and switch to the Profiling perspective
3. Start web service A with the "-XrunpiAgent" jvm argument
4. Start web service B with the "-XrunpiAgent" jvm argument
5. Start web service C with the "-XrunpiAgent" jvm argument
6. From Eclipse Profiling perspective, select "Run->Profile..."
7. From the Profiling configuration dialog select "Attach - Java Process"
and then click "New"
8. Select the host where the web serivces are running, then switch to the
"Agents" page
9. Select the java profiling agents and move them to the "Selected agents"
column
10. Change other profiling options if needed and click "Profile"

Samson,

Thanks a bunch for your answers/scenario. Hopefully, the WTP group will
post a response sometime in the near future -
http://www.eclipse.org/newsportal/article.php?id=9067&gr oup=eclipse.webtools#9067
I have some questions based on your responses:

1. If I was running all 3 web services on a single machine AND I wanted to
separate the data, would I need to install 3 JVMs (1 per web service)?

2. Does JVM = Java SDK? or can it be the J2RE?

Thanks again.

Ken

Hi Ken,

#1: One JRE/JDK installation is sufficient. You will need to start one
"java.exe" process per web service (i.e. one JVM per web service).

#2: A "JVM" is a "Java Virtual Machine". On Windows, one JVM corresponds to
one "java.exe" process. It could be either a J2RE (a "JRE") or a Java SDK (a
"JDK").
